CORDELL BANK: Blue Water Oasis SCRIPT NOAA/National Marine CORDELL BANK: Blue Water Oasis SCRIPT NOAA/National Marine Sanctuary logo VIDEO/MUSIC DIALOGUE Music and underwater breathing to build Jack Marshall: When we first arrived at suspense and tension the Bank // having never dove there before, I had no clue as to what was underneath me. // Diver’s view of underwater bubbles. We’re sliding on down into deep dark blue. // 3 minutes maybe// and wondering Schools of fish where’s the bottom? And then pretty soon And more fish we start to see an outline of fish. And we get down a little farther and there are absolutely incredible schools of fish. // millions of fish. Jack Marshall OC It is so hard to describe. I wanted to scream. I wanted to yell. I wanted to do something, but I didn’t want to spit my regulator out of my mouth either. Schools of fish Jack Marshall: Unbelievable. // Just fell in Label: on screen: Jack Marshall: Cordell love with the place. Absolutely fell in love Expeditions Diver with it. Super Title : Cordell Bank: Blue Water Oasis San Francisco life- Start with the hustle and bustle on the Trolley, Golden Gate Bridge trolley Narration: Not far from the hustle and bustle of the big city hidden from coastal views nearly 20 miles Cargo Ship heads out to sea west of Point Reyes lighthouse, lies an Point Reyes Lighthouse aerial underwater oasis that has only recently Pacific open water aerial been explored . On Cordell Bank boat it’s name is Cordell Bank National Marine Sanctuary. (this should be over the boat section) Getting here isn’t easy. And for scientists Dan Howard it poses a host of challenges. Superintendent Dan Howard: Cordell Bank is a very difficult place to study because of the off shore nature of the site. And our ocean in this area is typically really rough. So we have a couple months a year, typically September and October, when we can get out there and study the off shore environment. // On Delta Boat, see Dan board Dan Howard: All of this combines to make DELTA Submersible studying Cordell Bank a pretty challenging adventure. Narration: For scientists like Dan Howard, the rewards of working at Cordell Bank far out weigh the obstacles Delta POV- underwater descent Dan Howard: The thrill of going down in one of these manned-submersibles and exploring Cordell Bank is unique every single time that you go there. For instance, in 2001 our first exploration, the top of the Rockfish Bank was absolutely covered with juvenile rockfish. Young-a year rockfish; Rockfish tens of thousands of young-a year rockfish. The next year we went down expecting to see all the young-a year rockfish very few young-a year rockfish, but we were surprised to see Giant Pacific Octopus all Octopus over the reef going through mating behaviors that was absolutely unbelievable. The following year we went down expecting to see the octopus. Low and behold what did we come upon, hundreds Humboldt Squid of Humboldt Squid. All over the deeper reaches of the Bank. Dan Howard OC So we are coming to realize that Cordell Bank is just this phenomenally, dynamic area. We never know what we are going to see. We are always fascinated with the biological surprises that we see year after year exploring the Bank. Animation of the Bathymetry Narration: Cordell Bank is perched on the and the California Current continental shelf. Its western edge plummets more than a mile. This 4x9 mile rocky oasis rises up from the seafloor—and at its highest point reaches to within 115 feet of the surface. The rich California Current washes over the Bank, continuously supplying nutrients to the bounty of life here. This same current bathes the nearby Gulf of the Farallones National Marine Sanctuary [20] miles to the south. Animation of Cordell Bank plate tectonics shifting A favorite haunt among sealions and elephant seals, these craggy peaks mark one of the world’s foremost destinations for white sharks. Farallon Islands- aerials The islands also boast the largest concentration of breeding sea birds in the entire continental United States, great white shark sealions, elephant seals Seabirds take flight Farallon Island Aerial Open water Aerial Gold Rush footage and Period Music Narration: While the first documented discovery of the Farallons was in the 1500s, Historic Maritime images (these are due to be replaced) Cordell Bank was formally discovered during the California Goldrush when the US Coast survey undertook a series of offshore expeditions. Portrait of George Davidson During one expedition, the ship of expert hydrographer, George Davidson, became mired in a dense fog. Dropping a lead line to determine his Historic Maritime/fog images position, he found a shocking surprise. His depth registered a mere 30 fathoms (or 180 feet) half the depth he expected. He made a vow to return and conduct a proper survey. That survey, however, would fall to notice to mariners another man, Edward Cordell . .several years later. The Bank would later bear his name. Old film of CB Expeditions Narration: It was not until 1978, more On boat in Pacific Ocean than 100 years after its discovery that the first humans actually saw Cordell Bank for themselves. Bob Schmieder: After talking with quite a few people and finding out that this place was really unknown, Bob Schmieder I made a personal decision to try and go Founder of Cordell Expeditions there and learn something about it. And so I pulled a team together, a group of people who also wanted to do this. We worked for over a year before we succeeded in making our first dive. Old film – boat in open ocean Bob Schmieder: We didn’t have any good survey data and so we had trouble even finding Cordell Bank. // We were guided there as Edward Cordell was guided there, by birds sitting on the water // and sure enough we found a place that measured about 120 feet deep. Old film- diver jumps into water Narration:Along with Schmieder was veteran diver Jack Marshall Jack Marshall: Jack Marshall There were no landmarks anywhere. And I am wondering, is this boat going to be here when I get back from underwater. I swam over to the buoy, grab a hold to the line, put my mask on, and I poke my head under the water to take a look Old film- diver descent Jack Marshall: and all I see is this yellow rope going down about 100 feet. That is all I could see is it just disappearing into the blue. STOP JACK there Diver bubbles Schools and schools of fish Old film- reveal the Bank Bob Schmieder: And suddenly they parted and we could see, almost if you like, horizon to horizon this beautiful landscape. // And the thing that struck us most was the Colors of the Bank red colors at these great depths. At 120, 130, 140 feet Old film- underwater life and divers Jack Marshall: Every rock was covered with marine creatures and all kinds of colors, in yellows, in reds. The fish are darting in and out of all the rocks. // It’s almost indescribable. To do a dive on, what has to be, one of the most beautiful dive sites in the world. Jack Marshall Old film- return to boat after dive Narration: In recognition of its unique qualities, Cordell Bank became a National Marine Sanctuary in 1989. Watched over by the National Oceanic and Map of National Marine Sanctuaries Atmospheric Administration, NOAA, Somehow we need to pan a little quicker so Cordell Bank is one of 13 national marine that all the sanctuaries and monument can sanctuaries and one marine national be seen in this shot, it’s a little slow right monument. now.

  • Fish Wheels Lawrence Hall of Science
    Fish Wheels Lawrence Hall of Science This activity outline was developed for use in a variety of informal venues. By design, it provides the content, pedagogy and strategy necessary for implementation by both the novice and experienced informal educator. It is expected that this outline will be adapted and improved upon by the user. We welcome your feedback! Synopsis of the Activity Learners make fish adaptations wheels that allow them to examine different body structures (mouth shape/position/teeth, body shape, tail shape, and coloration patterns) and how their variations allow fish to be successful in their habitats. Based on this information, learners make predictions about the behavior and habitats of fish throughout the aquarium. Audience This activity is meant for a general audience. Younger learners will need some help putting together their fish wheels. Setting This activity can be set up in front of any size tank in an aquarium and then visitors can continue to make observations throughout the aquarium. Activity Goals • To engage the learner to think about the organism as if they were a biologist studying it. • To engage visitors to interact with aquarium exhibits. • To encourage learners to actively observe fish in aquariums and to make explanations based on evidence. • And through observations of body structure and coloration, draw some conclusions about the fish’s behavior and habitat (especially its movement, what it eats, strategies for defense, and where it lives in the water column). Concepts • Investigating the observable structures and behaviors of fish can provide a lot of information about how the fish lives and moves in its habitat.

  • Species Composition and Diversity of Fishes in the South China Sea, Area I: Gulf of Thailand and East Coast of Peninsular Malaysia
    S4/FB3<CHAVALIT> Species composition and Diversity of Fishes in the South China Sea, Area I: Gulf of Thailand and East Coast of Peninsular Malaysia Chavalit Vidthayanon Department of Fisheries, Bangkok 10900, Thailand ABSTRACT The collaborative research on species composition and diversity of fishes in the Gulf of Thai- land and eastern Malay Peninsula was carried out by R. V. Pramong 4 in Thai waters and K.K. Manchong, K.K. Mersuji in Malaysian waters, through otter-board trawling surveys. Taxonomic surveys also done for commercial fishes in the markets of some localities. Totally 300 species from 18 orders and 89 families were obtained. Their diversity are drastically declined, compare to the previous survey from 380 species trawled. The station point of off Ko Chang, eastern Gulf of Thai- land and off Pahang River shown significantly high diversity of fishes57 and 73 species found. De- mersal species form the main composition of the catchs. The lizardfish Saurida undosquamis, S. miropectoralis, the bigeye Priacanthus tayenus and P. macracanthus, the rabbitfish Siganus canaliculatus and hairtail Trichiurus lepturus were the most abundant economic species found in mast of the sampling stations. Fishing efforts were 34 hours and 49 hours for the cruises I and II, with average catch per hour of 12.04 and 34.79 kg. respectively. The maximum catch per hour was 175.3 kg in Malaysian waters, the minimum was 4.33 kg in Thai waters. The average percentage of eco- nomic fishes is higher than that of trash fishes in Malaysian waters, it ranged from 55.45 to 81.92 %.

Trinh1, Kristian Muri Knausg˚ard2( ), Arne Wiklund1, Tonje Knutsen Sørdalen3;4, Alf Ring Kleiven3, Lei Jiao1, and Morten Goodwin1 1 Centre for Artificial Intelligence Research, University of Agder, 4879, Grimstad, Norway 2 Department of Engineering Sciences, University of Agder 3 Institute of Marine Research (IMR), His, Norway 4 Department of Natural Sciences, Centre for Coastal Research (CCR) University of Agder, Kristiansand, Norway [email protected] Abstract. Our understanding and ability to effectively monitor and manage coastal ecosystems are severely limited by observation methods. Automatic recognition of species in natural environment is a promising tool which would revolutionize video and image analysis for a wide range of applications in marine ecology. However, classifying fish from images captured by underwater cameras is in general very challenging due to noise and illumination variations in water. Previous classification meth- ods in the literature relies on filtering the images to separate the fish from the background or sharpening the images by removing background noise. This pre-filtering process may negatively impact the classification accu- racy. In this work, we propose a Convolutional Neural Network (CNN) using the Squeeze-and-Excitation (SE) architecture for classifying im- ages of fish without pre-filtering. Different from conventional schemes, this scheme is divided into two steps. The first step is to train the fish classifier via a public data set, i.e., Fish4Knowledge, without using im- age augmentation, named as pre-training. The second step is to train the classifier based on a new data set consisting of species that we are arXiv:1904.02768v1 [cs.CV] 4 Apr 2019 interested in for classification, named as post-training.
